Eh, aside from the feet Vanilla models look fine to me. I am using UNP right now but Ill probably go back to just Detailed Bodies when I stop being lazy. Plus taste aside, its pretty immersion breaking to loot an older woman and have horrendous neck seams and body mismatch.
As far as I can tell, neither of them have complete armor/clothing replacers that attempt to keep the same style as vanilla. I haven't considered getting a body replacer yet because of this.
There is someone working on that for UNP, has quite a bit done so far but not everything. Duno about CBBE, but its popular enough.
